How to make a floating DirectX Child Window with Delphi? -

-

I have a Delphi project and the main form is a child window of another app parent application (coded in C ++ 3D game), there are two window states, the windowed and full screen in the window mode Delphi forms completely floating on top of the original application. It can be clicked, dragged around, there is no problem (CreateParams process of your main form using params.Style: = WS_POPUP; ): 

  Process TMyFormOpen (var Param: Tekta Param); inherited from; Start (ultimate); HandleToTheOtherApp: = FindWindow ('THE_OTHER_APP', zero); If HandleToTheOtherApp = 0 then ShowMessage starts ('Basic application not found'); Go out; End; Params.Style: = WS_POPUP; Params.WindParent: Handles on Audiobre; Params.WinClassName: = 'MyAppClassName'; End;

However if the original application is put in the Full Screen mode (it uses DirectX 9/10) then my Delphi form is hidden from the view. . It seems that it is still on the screen because it sometimes shines or not, but is not being underlined again.

If I click on the window (or where it appears) then it appears again to each other and then the game is taken out of full screen mode and then window mode Goes back in. Obviously there is something that does not like it about the form. The used form to appear in previous versions of this game, but possibly due to a change in DirectX version (my guess) does not appear anymore.

The form is not displayed Anything complex like 3D graphics, just basic controls like buttons and list boxes I've tried many window styles and have made it double buffer, everyone has no advantage. Maybe there is someone who has been able to show a window in these circumstances using a specific function, window style or header?

Does Delphi Form Direct DirectX

I do not think this can be done is.

When a DirectX video window becomes full screen, then DirectX takes over the full screen diagram (as you make a Windows Media Player full screen: all other apps disappear, and Sometimes the resolution changes)

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

sockets - Delphi: TTcpServer, connection reset when reading -

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
